It’s especially more popular with people who are trying to lose weight and are watching their diets strictly. However, it can be excruciating and exhausting to find the right drink for you.

In this article, I’ll be discussing the best sugar-free energy drinks I can recommend.

Let’s dive right in!

What Makes An Energy Drink Sugar-Free?

An energy drink is considered sugar-free if it contains less than 0.5 grams of sugar per its serving, according to the FDA. Contrary to popular belief, an energy drink doesn’t have to be completely sugarless for it to be labeled its claim.

Sugar-free products typically include both naturally occurring and added sugar, and are replaced with artificial sweeteners and sugar alcohols.

These energy drinks remain sweet as well as highly effective and popular among those who are trying to reduce weight.

What To Look For In Sugar-Free Energy Drinks?

The effectivity of the sugar-free energy drink would be a good place to start. Depending on its complete set of ingredients and its caffeine content, a sugar-free energy drink would rely on the factors for its energy boost.

Another, and arguably more important factor, would be its taste. Energy drink enthusiasts may have their own personal favorites and preferences according to flavor. After all, who would want to consume something that is horribly tasting?

Finally, price point may also play a factor in deciding what to look for in sugar-free energy drinks. You’d want the drink to be effective and tasty, without breaking your wallet.

Can You Consider Sugar-Free Energy Drinks Healthy?

Energy drinks at its core may not necessarily be considered healthy. They are, instead, efficient for your quick boost and as an aid in completing physical activities.

From a sugar standpoint, though, sugar-free energy drinks offer less complications than those that do contain added sugar.

For example, with sugar-free energy drinks, you won’t have to worry about your drink affecting your insulin or blood sugar levels.

Sugar-free energy drinks are considered to be healthy by looking at their sugar content. Keeping this in mind, too much sugar is a risk factor for diabetes, obesity, and heart disease, as research suggests.

Choosing a drink that is sugar-free or has relatively low sugar content is the key. The daily intake of sugar needs to be within a certain limit each day. According to the American Heart Association, the limit for added sugars are as follows:

  • 150 calories daily or 9 teaspoons for men
  • 100 calories daily or 6 teaspoons for women
